extendedinfo	string	No		A custom error code that you supply.
object	any	No		Requires the value of the cfobject tag name attribute. Throws a Java exception from a CFML tag. This attribute is mutually exclusive with all other attributes of this tag.

    throw(message="Oops", detail="xyz"); //CF9+
} catch (any e) {
    writeOutput("Error: " & e.message);
} finally { //CF9+
    writeOutput("I run even if no error");
}
